[3dem] tweezers for vitobot

[John Rubinstein, U of T]

Hi Isabelle,

We've been modifying our own tweezers for some time (since our Vitrobot 
went through a phase of mangling them on a semi-regular basis).  There 
are different mounting blocks that I've seen used with vitrobots: one 
type takes completely unmodified Dumont L5 tweezers (probably the older 
version).  The other type requires that you get the L5 tweezers cut to 
the right size by a workshop.  Our vitrobot came with one of each type 
of block but we got a spare of the second type from our outstandingly 
helpful FEI engineer.  The red "loctite" on the forceps can be removed 
with a Bunsen burner.  If you have the type of mounting block that 
requires cutting the tweezers, I suggest simply taking the old damaged 
tweezers to the workshop so they can use them as a guide.  For safety, 
you should probably also use some loctite after putting the new forceps 
in to ensure that the screws don't become loose during use.  In Montreal 
you should be able to find loctite at a Canadian Tire store.

Best regards,
John
